Pulmonary edema is an accumulation of leaked out of blood vessels in the lung fluid fabrics.Pulmonary edema is always there as a symptom or complication of another serious illness.
Human lungs are made up of a huge number of alveoli, braided extensive network of capillaries.It is in these gas exchange occurs, necessary for normal functioning of the body and human life.Pulmonary edema occurs when the alveoli falls liquid instead of air.For example, in case of damage.Accumulation of fluid in the alveoli of the lungs can cause very serious consequences related to violation of human intake of oxygen and removing carbon dioxide from it.Incorrect handling of light leads to the development of oxygen starvation of the body.
The causes of this symptom may be a few.Experts identify two main types of lung edema.One of them - cardiogenic associated with the presence of such diseases as heart failure.Non-cardiogenic pulmonary edema is not related to irregular heart function and can be caused by a host of
In heart failure there is impaired cardiac function, followed by an increase in pressure in the pulmonary blood vessels, which contributes to fluid ingress of them right into the alveoli.Stagnation of blood in the pulmonary blood vessels as a result of arrhythmia, myocardial infarction, heart disease can also cause the development of pulmonary edema.
liquid has been spilled into the pulmonary alveoli can occur as a result of damage to the lungs, brain injury, the presence in the body of severe pulmonary infection, eclampsia in pregnant women, poisoning potent toxins, cocaine / heroin rapid ascent to a height greater than three kilometers.
often to the development of pulmonary edema resulting in violation of kidney function associated with the inability to excrete fully liquid.Patients with various kidney diseases shows dialysis.Neurogenic pulmonary edema is usually observed with intracranial hemorrhage at the time of injury or during surgery on the brain.
Symptoms of pulmonary edema
main symptom occurrence of pulmonary edema is a difficulty in breathing, shortness of breath.In that case, when the disease develops slowly, shortness of breath arises spontaneously, speed and alternates with severe fatigue.It does not matter what people are currently doing.Signs of fatigue can occur even in a moment of relaxation.In the case of acute pulmonary edema, a person begins to choke, often similar to a condition called "lack of oxygen".For obvious symptoms of edema include: the emergence of dizziness, fainting, sudden shortness of breath.pulmonary edema may be accompanied by cough, nervous excitement of the patient, the appearance of his cold feelings.
specialist can reveal pulmonary edema when listening to the patient's chest with a stethoscope, as the disease is accompanied by the appearance of uncharacteristic for healthy human breath gurgling sounds and wheezing.
of lung edema involves the binding and rapid hospitalization from any cause.In the case of heart failure at the current sluggish pulmonary edema fairly routine visits to a specialist.Supervision of patients with pulmonary edema engaged therapist and pulmonologist.Diagnosed disease is quite simple - the results of chest X-rays.On an X-ray of the patient, any specialist can immediately see an excessive illumination of light fields, filled with liquid.To establish the cause of the swelling X-rays may not be enough.In this case, you may need catheterization procedure - measuring the pressure in the vessels of the lungs by introducing a special vein in the chest tube - a catheter Swan-Ganz.
Treatment of pulmonary edema
Treatment of pulmonary edema depends entirely on the degree of its severity and the causes.The swelling that developed as a result of heart failure, can be completely cured with the use of diuretic drugs (diuretics).In cases of minor non-progressive pulmonary edema treatment can be performed at home with the obligatory visit to the doctor.If the disease arose spontaneously, progresses rapidly and can not be cured by conventional oral medication, the patient is subject to hospitalization and administration of diuretics in his body through the blood, that is, with the use of injections or IVs.
If the cause of the accumulation of fluid in the alveoli of the lungs is an infection, treatment is with antibiotics.In renal failure, as noted above, illustrates dialysis - artificial removal of body fluid using special devices and apparatus (catheter fistula, depending on the type of dialysis).
severe cases, pulmonary edema requires connecting the patient to a ventilator, which supports his breath at the appropriate level, is carried out by experts on the treatment and action to address the underlying causes of the disease.
Pulmonary edema is a very dangerous symptom of many diseases.In most cases, an attack of shortness of breath and lack of oxygen occurs in a patient in the early morning hours.It can provoke hypothermia, excessive exercise, stress.The cause of pulmonary edema in patients with heart failure may even become a nightmare at night.Today, lung edema refers to a number of fatal complication of many diseases, so the appearance of shortness of breath should immediately call the branch "Ambulance" and not to take any independent efforts to get rid of a dangerous symptom.In the case of the provision of timely medical care the outcome in almost all cases is favorable.
